4 Ton Biogas Fired Steam Boiler

  • CHAPTER 3 COMBUSTION CALCULATION

    Gaseous propane of 88 kg/hr is burned in a boiler with 10% excess air to produce 1200 kg/hr of steam at 0.1 MPa and 150oC. The percent conversion of the propane is ; of the fuel burned, 90% reacts to form CO2 and the balance to form CO. The temperature of combustion air, fuel and water entering the boiler is assumed at 25oC.Learn More

    Class D - Diesel or gas oil. Class E - Light fuel oil. Class F - Medium fuel oil. Class G - Heavy fuel oil. Oil began to challenge coal as the preferred boiler fuel in the UK during the 1950s. This came about in part from the then Ministry of Fuel and Power's sponsorship of research into improving boiler plant. The advantages of oil over coal Learn More

  • How Boiler Efficiency can Affect Stack Temperature

    Based on the numbers posted the boiler is less efficient by 2 or 3 percent because the higher flue temperature means less heat is being transferred. The draft over the fire should be checked. Ideally it should be -.01"W.C. The O2 reading is also a little high 4-5% would be more ideal.Learn More

That's a recommended "standard" as I understand it, poorer fuels would most likely have a higher flash point leading to a higher recommended temp I would think.Learn More

    The VariflameTM burner delivers high-efficiency performance in gas-fired package boilers with NOx emissions as low as 20 ppm (41 mg/Nm3) at 3 percent O2. Using advanced air-fuel staging techniques, the Variflame burner can operate with or without flue gas recirculation (FGR). Reduces NOx, CO, VOC and particulate emissionsLearn More

  • Improve Your Boiler's Combustion Efficiency

    From the table, the boiler combustion efficiency is 78.2% (E1). Tuning the boiler reduces the excess air to 9.5% with a flue gas minus combustion air temperature of 300°F. The boiler combustion efficiency increases to 83.1% (E2). Assuming a fuel cost of $8.00/MMBtu, the annual savings are: Annual Savings = Fuel Consumption x (1–E1/E2) x Fuel CostLearn More
